UITableView tapgesture行爲

Question

當我點擊我的表格視圖時，它將觸發touchesBegan和touchesShouldBegin。但是，我的視圖單元上也有一個UIPanGestureRecognizer，並且在平移單元時，點擊其他單元不會觸發touchesShouldBegin。

我需要的原因touchesShouldBegin是因爲我想在單元格被平移時停止觸摸。有其他方法可以用來做到這一點嗎？我曾嘗試將allowsMultipleSelection設置爲false和true。

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 
    print("This will always be printed") 
} 

override func touchesShouldBegin(_ touches: Set<UITouch>, with event: UIEvent?, in view: UIView) -> Bool { 
    print("This will only be printed when no cells are being panned") 

    return true 
} 

Answer 1

嘗試將UITableView的delaysContentTouches屬性設置爲true。

您也可以嘗試添加一個UIGestureRecognizerDelegate您UIPanGestureRecognizer並：

extension MyViewController: UIGestureRecognizerDelegate { 
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool { 
    return true 
    } 
}
